取付具10において、被当接面2に対して押し付けられることで、この被当接面2に拡がる液体又は固体を拭き取り、又は掻き取る弾性部材よりなる一方向に長いブレード3を被当接面2に対して所定の押圧力で押し付けるように支持するワイパーアームに支持される第1支持部材11と、第1支持部材11に対して板バネ14を介して支持され、ブレード3の基端側が取り付けられる第2支持部材13とを設ける。板バネ14を、ブレード3が被当接面2に押し付けられて相対的に摺動するときに、第2支持部材13を第1支持部材11に対して移動させる摩擦力に対して反力を加えるように取り付ける。
An attachment tool 10 is provided with: a first support member 11 supported by a wiper arm which supports, so as to be pressed against an abutment surface 2 at a prescribed pressing force, a unidirectionally-long blade 3 that is made of an elastic member and that, when pressed against the abutment surface 2, wipes off or scrapes off liquid or solid spread on the abutment surface 2; and a second support member 13 which is supported on the first support member 11 via a leaf spring 14 and to which the base end side of the blade 3 is attached. The leaf spring 14 is attached in such a manner so as to exert a reaction force in response to a friction force causing the second support member 13 to move with respect to the first support member 11 when the blade 3 is pressed against the abutment surface 2 so as to make a sliding movement relative thereto.
